Unless your a sucker for pain & suffering <<"just kidding there", you might want to stay away from any mods on this model.... f..y..i... here's something I found*
I have recently come across this old aptiva at work and I instantly was inspired to obtain it and do a nice case mod. But, I am rather inexperienced at case modding and suggestions would be helpful. I will be posting a worklog as soon as the parts come in from newegg. Here is the plan, to take this old aptiva which is a rather unique design utilizing an external SCSI enclosure to house its optical and floppy drives as well as be a really nice looking case because of its lack of clutter. I wish to maintain all of this when I modify this machine. The objective is to either formulate an HTPC or at least a more powerful machine within this case. The problem: I wish to keep the external drive device, but there is no scsi card that is pci that has a similar connector (that I know of) and the machine has a strange board design so cutting will be neccessary to fit an ATX board in the machine and due to the position of the power supply I will probably need to use a micro ATX board. Any suggestions / experiences would be helpful. Again I will post a work log as soon as i begin.
